StockSteer reads Shopify and Amazon together and answers the question single-channel tools can't: which channel should get this stock, and how many units — with the math shown, every time.
One sales CSV in → diagnosis in your inbox within 48 hours.
No account. No OAuth. Read-only — we never touch your listings.
Shopify and Amazon FBM are selling the same 88 units. Combined velocity 11.2 u/day — first channel to spike breaks the other.
Not a dashboard. A short, human-checked report with the handful of calls that actually move margin this month.
Every SKU's sales velocity and days of cover, split by channel — numbers that rarely get put side by side. The imbalances are usually immediate and expensive.
CARA-BLK Shopify 64d · FBA 9d · imbalance 7.1×Concrete transfer calls — “send N units to FBA by this date” — weighted by velocity and margin after each channel's fees. Every number expands into its arithmetic. If you disagree with an input, you can see exactly which one.
Where Shopify and Amazon FBM are quietly selling the same pool of units, and the projected date each channel goes dark if nothing changes.
TENT-2P shared pool 88u · oversell ETA 8 daysIf your history is too thin to support a recommendation (under ~90 days on a channel), the report says so and explains what it can support instead. We'd rather decline than pad thin data into confident advice.
A Shopify order export, an Amazon order or FBA report — or both. Twelve months is ideal; ninety days is the floor. One channel is fine to start.
Strip the buyer columns before uploading. We don't want names, addresses, or emails — the diagnosis only needs SKUs, dates, quantities, and prices.
Per-SKU velocity by channel, days of cover, margin after channel fees, shared-pool exposure. A human checks every report before it leaves — this is a diagnosis, not an auto-generated PDF.
Two kinds of calls — move stock, and risk warnings — each with its arithmetic shown. What you do with them stays entirely in your hands: StockSteer never writes to your stores.
Inventory tools built for Shopify treat Amazon as something to sync in later, if at all. But the same unit can't be in two places: every carton you keep at your 3PL is a carton FBA can't sell, and every unit you send to Amazon stops covering your DTC orders.
That trade-off has a price on both sides — different fees, different velocity, different margin per unit. Single-channel tools can't see it, so the decision gets made by habit: whoever shouted about stockouts last.
Allocation is a margin decision, not a sync problem.
StockSteer recommends; it never edits listings, quantities, or orders. Not now, not in the product.
We ask you to strip customer columns before uploading. If any slip through, we delete them.

The diagnosis costs nothing and obligates nothing. If it's useful, we'll talk about what comes next. Terms
The rule is simple: reading your numbers is free, acting on them is paid.
The one-off report described above. No card, no account, no obligation — during our pre-launch period this is how we learn and how you evaluate us.
When the product launches: channel-by-channel coverage and oversell/stockout warnings from your connected stores, in a daily email.
Daily allocation calls — where to move stock, how much, with the math shown — priced by catalog size. Final tiers will be published at launch; this range is our current plan, and diagnosis recipients lock in early-access pricing.
Upload a sales CSV. Within 48 hours you'll have channel-by-channel coverage, transfer calls with the math shown, and any oversell risks we find.
Prefer email? Send your CSV straight to liu_ky@hisuntech.com — same result.
Shopify's order export CSV and Amazon's order/FBA reports (CSV or tab-delimited) work as-is. Anything with SKU, date, quantity, and price per row is usable — from any system. If you're unsure, send what you have and we'll tell you if it's enough.
No, and we'd rather not have it. Please remove buyer names, addresses, and emails before uploading. The diagnosis runs entirely on SKUs, dates, quantities, and prices. If personal data slips through anyway, we delete it.
The diagnosis is free, with no obligation. The ongoing product — daily email reports with allocation calls and risk warnings, fed live from your Shopify and Amazon accounts — launches with a free diagnostics tier and a paid decisions tier, currently planned at US$29–79/month by catalog size. Diagnosis recipients get first access and early-access pricing.
Never. StockSteer is advisory and read-only by design — for the diagnosis we don't even connect to your stores, we just read the file you send. The launched product connects with read-only permissions and keeps the same rule: it recommends, you decide.
Yes, with reduced scope: you'll get velocity, coverage, and stockout ETAs for that channel. If you're planning to add Amazon (or DTC), the diagnosis will also show what your current numbers suggest about splitting stock when you do.
It's used to produce your diagnosis and for the follow-up conversation with you, then deleted on request — one email is enough. We never sell it and never use it to train models without your explicit consent. Details in the Privacy Policy.
